Stop Android MediaPlayer automatically launched by webpage within WebView

Question

one of the activities of my Android app contains a WebView that displays the GrooveShark player webpage. When the user taps on the play button of the webpage the activity automatically launches a default MediaPlayer that plays the track. Everything works fine, the problem arises when the user closes this activity and the MediaPlayer, although is not playing the track anymore, it remains alive... even when the app is closed, the MediaPlayer is still alive. The only way to kill it is by forcing the app to stop... I doesn't seem a big deal but in some devices when the user hangs up after a phone call, this "zombie" MediaPlayer all of a sudden starts to play the track even though the app was already previously destroyed... This is a summary of the code of my Activity: ``` @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_song); myWV = (WebView) findViewById(R.id.webview); WebSettings webSettings = myWV.getSe…

After struggling with a similar issue, I finally found a solution. It appears that if the AudioService does not have focus when you close the Webview, it is not paused. This causes severals issues (another player cannot start playing etc.)

The only solution that worked for me is:

```
@Override
protected void onPause() {
    super.onPause();

((AudioManager)getSystemService(
            Context.AUDIO_SERVICE)).requestAudioFocus(
                    new OnAudioFocusChangeListener() {
                        @Override
                        public void onAudioFocusChange(int focusChange) {}
                    }, AudioManager.STREAM_MUSIC, 
                    AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);

}
```

This will cause the current player to be paused/killed (not sure which) when going down and solve all of my issues / problems. Hope it could help you too...
